It can complete the rice husking and brown rice whitening in a short time and at one time, and then weigh and calculate the whole polished rice rate by cooperating with the balance. This product is suitable for testing the quality of rice, millet and millet in grain, seed, agriculture, grain colleges, commodity inspection and scientific research departments. In the process of processing, in order to give pressure to the rice (so that the rice husk can be filtered out from the screen), the existing small rice polishing machine, such as the Chinese patent with patent number 201220718960.8, passes the pressure rod through the pressure lead, and one end is hooked on the hook part of the machine, and a heavy hammer is hung on the other end, and the heavy hammer gives pressure to the pressure lead through the lever principle; this structure is very unsafe in use, because the pressure ball will shake during processing, and when the shaking amplitude is too large, the heavy hammer may be thrown out, affecting the safety of the user; at the same time, when processing different amounts of rice, it needs to adjust the corresponding position of the heavy hammer, which is cumbersome to use; therefore, it is necessary to improve it.

Inside the outer body 10 is a driving motor controlled by a control panel 11, and the control panel 11 has various operation buttons, through which various instructions can be issued to the driving motor to meet the use requirements; the driving motor is provided with a cooling fan, which can quickly dissipate the heat generated by the driving motor during operation. A roller is connected to the driving motor, and the roller is connected to a rice polishing knife 21 in the polished rice bin 20 to control its rotation. The precision bin 20 is provided with a voltage stabilizing device, a rice polishing knife 21, a screen 22, a receiving hopper 23 and a thallium pressure lead 24. The rice polishing knife 21 is located in the rice polishing chamber and removes the outer shell of the rice grains through the control of a driving motor; the receiving hopper 23 is located directly below the rice polishing chamber and is a removable structure, which is used to receive the rice husks broken by the rice polishing knife, and after pouring out the rice husks, to receive the processed rice grains. The removable structure of the receiving hopper 23 is as follows: there are outwardly protruding edges on both sides of the receiving hopper 23, and there is a track at the bottom of the rice polishing bin 20, and the edges are movably connected to the track. The screen 22 is located at the bottom of the rice polishing chamber and just above the receiving hopper 23 to filter the rice husks; the screen 22 can rotate in the rice polishing chamber by rotating, and its rotating structure is: it includes a knob 40 and a circular rotating plate 41, the circular rotating plate 41 is positioned on the precision bin 20 and can rotate around its axis, the knob 40 is fixed to the middle of the outer side of the circular rotating plate 41 and its axis coincides, the screen 22 is fixed to the inner side of the circular rotating plate 41 and is linked with it; during operation, the rice husks crushed by the rice polishing knife 21 by the pressure of the thallium pressure 24 will fall into the receiving hopper 23 through the screen 22, and after the processing is completed, the receiving hopper 23 is pulled out and poured out and the rice husks inside are cleaned so that the rice grains can be placed next. Above the polished rice chamber, there is a pressure lead 24 for applying pressure to the rice, and there is a pressure stabilizing device on the pressure lead 24, which includes a sleeve 25, a pressure stabilizing spring 26 and a stop rod 27. A pressure tube 29 is fixedly connected to the upper end surface of the pressure lead 24, and a positioning hole with an opening is provided in the pressure tube 29. A positioning groove is provided on the side of the pressure tube 29 for allowing the clamping column 28 to be positioned horizontally and vertically thereon. The positioning grooves are a horizontal positioning groove 31 and a vertical positioning groove 32 that are interconnected, and a "]"-shaped structure is formed therebetween; the clamping column 28 cooperates with the horizontal positioning groove 31 and the vertical positioning groove 32 for positioning. The clamping column 28 is a telescopic structure, and its structure is as follows: there is a screw hole at the bottom of the sleeve 25, and there is a threaded portion on the outer peripheral surface of the clamping column 28, and the threaded portion is screwed into the screw hole; or there is a through hole at the bottom of the sleeve 25, and the rear end of the clamping column 28 is positioned in the through hole, and there is a return spring inside the clamping column 28 that allows its front end to freely extend and retract. The sleeve 25 is sleeved on the outside of the pressure tube 29, and the pressure stabilizing spring 26 is inserted into the inside of the pressure tube 29, with one end of the spring abutting against the bottom of the pressure tube 29 and the other end of the spring abutting against the bottom surface of the sleeve 25 to apply pressure to the pressure lead 24 during operation.The sleeve 25 is provided with a positioning support rod 30 , and the blocking rod 27 is provided with a bayonet with an opening. The positioning support rod 30 is engaged in the bayonet during use to position the sleeve 25 in the longitudinal direction.

[0014] During use, the pressure lead 24 is first taken out from the refined rice bin 20, and the pressure stabilizing spring 26 is placed in the pressure tube 29, and then the sleeve 25 is sleeved on the outside of the pressure tube 29, and the clamping column 28 is clamped in the lowest horizontal positioning groove 31, so that the pressure stabilizing spring 26 is in a compressed state; then the pressure lead 24 is placed in the refined rice chamber to give internal rice pressure, and then the sleeve 25 is rotated to move the clamping column 28 into the vertical positioning groove 32. At the same time, the positioning support rod 30 will be clamped in the bayonet to prevent the sleeve 25 from moving upward due to the action force of the pressure stabilizing spring 26; as the rice husks are separated from the screen 22, the pressure lead 24 will move downward in the refined rice bin under the pressure of the pressure stabilizing spring 26 until Until the rice polishing operation is completed; after the rice polishing operation is completed, the receiving hopper 23 is first taken out from the bottom of the rice polishing bin, the rice husk inside it is cleaned, and then it is returned to the bottom of the rice polishing bin, and the knob 40 is turned to rotate the screen 22 counterclockwise by 180° to pour the polished rice on the screen 22 into the receiving hopper 23, and the driving motor is started to work briefly to throw out the rice grains in the rice polishing bin; finally, the screen 22 and the receiving hopper 23 are taken out from the rice polishing bin in turn, the rice grains adhering to the screen 22 are cleaned onto the selection screen, and the rice grains in the receiving hopper 23 are poured onto the selection screen for screening, and the polished rice mass obtained after screening is divided by the rice mass before processing to obtain the polished rice rate.
